IMPROVEMENT IN SOLDE'RING SlPIRAL BANDS.

The Schedule referred to in these Letters Patent and making of the sam.

To whom it may concern Be it known that I, ELIJAH H. RUssELL, of the city and county of Providence and State of Rhode Island, have invented a new and usefnl'lmprovement in Metallic Elastics; and' I do herebyV declare that the following specification, taken in connection with the drawing making a. part thereof, is a full, clear, and exact description of the same.

My improvement relates to a means whereby the two ends of a coiledwire elastic can be arranged so that they can be joined permanently by means ot' solder, the article being nearly as flexible at the joint as at any other point.

In the drawingn lFigure 1 is a view in perspective of an elastic made of coiled i'vire.

Figure 2 is a longitudinal section at the joint.

Figure 3 is an elastic and ilexible core-piece, used as the link of connection. f

Heretofore elastics of this .kind have had their' ends furnished with a hook and eye, no means having been devised for uniting,r the ends permanently togather.

A, fig. 2, represents an elastic which is to be united at the line a:

I make a helical coil precisely like that from which the elastic is made, with the difference that its diameter is the same as the interior diameter of thecoil.

I take a short section, B, iig. 3, of such last-named coil, and, as it is ofthe same size of wire as that from which the elastic is made, and has the same' number of oonvolutions to the inch, it can be entered as a screw into the open ends of the elastic, and span the- What I claim as my invention, and desire to secure by y[letters Patent, isv The employment, in combination with an elastic of the character described, of an interior core or threaded dowel, B, soldered to the elastic, as a means of securing the two ends of the elastic together, substantially as described.
